Well seems like cursory searches only return that article, but I'd recommend searching for general A/D design theory as well. I started writing much too much about my own theory on payload, but I don't actually know what you are looking for so I'll hold off unless there is interest.

Thank you, I'll be sure to look into that article. I've already been taking notes on the recompiled maps and been working with the game library. However, I'll probably be taking this slow and not rush a product.
